NEW YORK

MAY 2003




U.S. GEOLOGICAL SURVEY, WRD New York District, Troy, NY WATER RESOURCES REVIEW AND CURRENT CONDITIONS STATEMENT FOR MAY 2003 Prepared June 2, 2003 Troy Subdistrict--Summary Report Provisional streamflow conditions at sites monitored and included in this report in eastern New York were in the normal to excessive range. Conditions at all these sites increased from the previous month. The sites in the excessive range were located in the western Adirondack Mountain region in northern New York. The percent exceedence at two of these sites, Independence River at Donnattsburg and Little Salmon River at Bombay, decreased over 60% from last month when these sites were in the deficient range. The total New York City reservoir system was at 100.1 percent of capacity on May 30; normal for this period is 100.0 percent of capacity. Ithaca Subdistrict--Summary Report Provisional streamflow conditions at sites monitored and included in this report for western New York remained in the normal range except for sites at Tonawanda Creek at Batavia and Flint Creek at Phelps which increased from the deficient range to the excessive range. Oneida Creek at Oneida remained excessive for the third consecutive month. Coram Subdistrict--Summary Report Mean flow at Connetquot Brook near Central Islip was in the normal range for the sixth consecutive month. ___________________________________________________________________________________________

## Reference period is 1978-2000 ** Excessive # Note: Flow statistics based on data collected through May 31, 2003. _____________________________________________________________________________________________ NOTES, DEFINITIONS, ETC. Percent exceedence is, for example, the percentage of November monthly mean discharges for period of record equal to or greater than the current November monthly mean discharge. Statistics for the "Index Streamflow Stations" table are for the 30-year reference period 1971-2000. All other statistics used in report are based on the period of record at the site. Median = 50th percentile, which means that, for the period of record included in the analysis, 50% of the values are greater than the median and 50% are less. Deficient range = values below the 25th percentile - for the period of record included in the analysis, 75% of the values are greater and 25% are less than this value. Excessive range = values above the 75th percentile - for the period of record included in the analysis, 25% of the values are greater and 75% are less than this value. Normal range = values between the 25th and 75th percentiles.
